This forum is most useful and thanks to all with my questions so far. 
I intend to fly back to the US from the UK on Jan 2nd '05. I will be in PE but my G/Friend will be in Economy (she is a lot thriftier than I am
) - If she's on a cheapo ticket in the back but has by then over 10,000 miles, can she do a one way upgrade from Econ to PE to sit with me?
The upgrades guide is great on this site BUT, there is a question of whether being on some Econ tickets makes it hard to do a mileage upgrade.
Question: what are the chances of her getting upgraded with her miles at the airport? Are they really picky or are they generally very liberal?
Thanks,
P.S. Is there an option if the answer is no for me to buy her an upgrade, if so is it a good price or ridiculous? I only ask as once I asked to upgrade on BA from WT to WT+ and they quoted 900GBP!!! [:0] [BA wonders why it's loosing market share]
